    Hi Sheshnarayan,

    Have you tried using PowerShell to delete the disk?

    Find and delete unattached Azure managed and unmanaged disks

    https://learn.microsoft.com/en-us/azure/virtual-machines/windows/find-unattached-disks

    Get-AzDisk 
    

    Find the disk you want deleted, and use the following command to delete it:

    $disktoRemove = Remove-AzDisk -Force
    

    If this is helpful please accept answer.

    Hello Sheshnarayan Patel (TATA CONSULTANCY SERVICES LTD),You need to identify the Persistent Volume (PV) and Persistent Volume Claim (PVC) that are using the disk.

    Use kubectl to list PVs and PVCs and find the ones associated with your disk.

    kubectl get pv

    kubectl get pvc --all-namespaces

    If the PV was not automatically deleted after removing the PVC, you might need to manually delete the PV.

    kubectl delete pvc <PVC_NAME> -n <NAMESPACE>

    Deleting the PV does not delete the underlying disk in Azure, and you need to make sure the data is not needed.

    kubectl delete pv <PV_NAME>

    you may need to manually detach it from the node in the Azure portal or using Azure CLI, especially if it was attached outside of Kubernetes' management

    Using Azure CLI to Detach the Disk.

    az vm disk detach --resource-group <ResourceGroupName> --vm-name <VMName> --name <Disk Name>

    Delete the Disk Using Azure CLI.

    az disk delete --name <DiskName> --resource-group <ResourceGroupName> --yes --no-wait
